We describe the characteristics of a novel optical material developed in our laboratory, a fractal/microcavity composite. Both components of this composite exhibit resonance behavior whereby the amplitudes of spectral emissions, generated by molecules either adsorbed onto the composite or located remotely from it, are significantly enhanced. In the composite, the individual enhancement factors combine multiplicatively with the result that spectral emissions are enhanced by an extremely large factor. In particular, the extremely large enhancement factors facilitate the generation of nonlinear optical processes in the composite, which may be exploited in the fabrication of ultra-sensitive detectors.
